The Potential For Reducing N Fertilizer Inputs For Corn Production In The First Year Following Alfalfa, Earl Creech, Grant Cardon, James Barnhill, Jody Gale, Clark Israelsen, Boyd Kitchen, Mark Nelson, Mike Pace

All Current Publications

The objectives of the project reported in this fact sheet were to 1) examine current post-alfalfa N fertilizer credit guidelines and investigate the potential to further reduce N fertilizer rates (if possible) on first year corn after alfalfa across Utah, and 2) accordingly update the USU Extension corn management recommendations and promote grower awareness and adoption of the new guidelines.

Managing The Spread Of Alfalfa Stem Nematodes Ditylenchus Dipsaci: The Relationship Between Crop Rotation And Pest Re-Emergence, Scott Jordan

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Alfalfa is a critical cash/rotation crop in the western region of the United States, where it is common to find crops affected by the alfalfa stem nematode (Ditylenchus dipsaci). Understanding the spread dynamics associated with this pest would allow end-users to design better management programs and farming practices. This is of particular importance given that there are no nematicides available against alfalfa stem nematode and control strategies largely rely on crop rotation to non-host crops or by planting resistant varieties. I present a basic host-parasite model that describes the spread of the alfalfa stem nematode on alfalfa crops. With this …

The Effect Of Deposition From Static Rocket Tests On Immature Corn, Alfalfa, And Winter Wheat, Eric Curry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

ATK tests the performance of large solid rocket motors (SRMs) at their facility located in Promontory Point, Utah, USA. During these tests, an estimated 1.5 million kg (~3.3 million lbs.) of entrained soil and rocket exhaust are sent skyward in a cloud that can travel as far as 10-12 miles from the test site. As the cloud cools deposition known as Test Fire Soil (TFS) can settle on local crops. Farmers in the area have voiced concerns about the effects of TFS on their crops.

To address the concerns, I looked at the effect of a typical TFS deposition loading …
